The President Vanishes depicts how a few men of the economic elite try to force the President to take part in a war in Europe. In response to the President refusal, the lobby starts to bribe Senators and to orchestrate a campaign of agitation & propaganda in order to infuse the people with belligerent feelings. This looby is an embodiment of the Committee on Public Information during World War I, clearly criticized in the film. The film even warns about the raising of fascism in the United States during the economic crisis of the early thirties.
